Atletico
are on the verge of an historic season which could finish with the
Primera Division title and a Champions League final in Lisbon on May 24,
with Simeone responsible for much of the progress the club has made in
his two-and-a-half years as boss.

'I'm not thinking about what we've achieved,' Simeone said.

'I'm not focusing on where we are at the moment, I'm just focusing on keeping on moving forward.

'I'm not comparing Chelsea, a team that won the Champions League two years ago, with Atletico Madrid.

'In
the end the best team will win and I believe with our hard work, I
believe we can do well and maybe try to get a positive result.'

Atletico goalkeeper Thibaut Courtois is set to play at Stamford Bridge for the first time.
